WELDING

Arc welding is most widely used fusion process for joining metals. In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work and an electrode (stick or wire) that is manually or mechanically guided along the joint. However, joining metals requires more than moving an electrode along a joint...

Arc welding is most widely used fusion process for joining metals. In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work and an electrode (stick or wire) that is manually or mechanically guided along the joint. However, joining metals requires more than moving an electrode along a joint. Besides some form of arc shielding, welder ‘s knowledge and experience play the crucial role. Therefore, our welders are strictly kept in groups concerning materials and processes. As for the materials we have specialist for mild, stainless and galvanized steel, as well as aluminum. Each of these materials our welders join or repair by shielded metal arc (SMA), metal inert gas (MIG), metal active gas (MAG) and tungsten inert gas (TIG) processes. Needless to emphasize, that each and every single welder is certified by some IACS member class society, while all the procedures are determined and controlled by international welding engineer (IWE).

CORROSION PROTECTION

An understanding of corrosion and development of a corrosion engineering science has come about due to the need to protect materials from disintegration by normal breakdown processes. Atmospheric rusting, chemical solution, oxidation, and galvanic coupling reactions, are the means by which materials return to their original state. Tremendous amount of energy used to convert them from their original form to one usable by humans remains latent in the material and is released at every opportunity as the material reverts to a state of equilibrium with nature. Everyone in modern society is affected, in some way, by this energy release phenomenon, or corrosion. Control of this reversion process is the goal of corrosion engineering.
